Les gets it - it's Goatchurch. It was an anniversary but not my wedding. It actually marked 40 years since my first caving trip - in Goatchurch, of course. The four of us on the trip all used 'stinky' carbides to re-create the atmosphere, and the aroma, of that first trip on the 5th February 1971.

My thought train: " I dunno where these other caves are for the hot/warm clues...weren't there some photos of the one under Hunters that kind looked muddy and small like that? huh, no one has said that one yet...Why the heck not guess it then?"

erm erm erm uhhh *finds photo*

Ahh here we go.

Cave name AND location, please.No this is not photoshoped, I was playing with steam painting since the LED's on my corona trend blue.
